Abstract

PURPOSE: To provide a temporary staircase by which workers can ascend/ descend any position of a slope and to stabilize a scaffolding to enable work on the slope safely. CONSTITUTION: Two sets of bearing bodies 2 and 2 making a pair of right and left stair strings 1 as a set are arranged in parallel with each other, and both bearing bodies 2 and 2 are borne on a plurality of treads 3 arranged at equal intervals in the longitudinal direction of the bearing bodies 2 to form a ladder-like staircase. The treads 3 are pivoted between right and left stair strings 1 in a rotable manner, and both bearing bodies 2 and 2 are movable in parallel with each other in the longitudinal direction. Expandable legs 8 whose length is adjustable are provided to at least each one end of both stair strings 1 and 1 of a set of bearing bodies 2. Holes for connecting with one of the bearing bodies 2 of the treads 3 are formed in the shape of a slot.

どの危険性が伴う。Since the slope is slanted, there is a risk of injury due to slipping and falling or slipping of the foot when directly moving up and down when performing work such as unloading. . Therefore, we sometimes use fixed stairs installed on the slope, but the number of fixed stairs is small, so there is not always a fixed staircase at the place where we want to work, and detouring causes considerable labor. There is also. For that reason, there are also cases where you can use the assembly-type temporary stairs, but since the assembly-type temporary stairs require you to assemble the stairs before work,
It takes time and effort. In addition, when performing work such as mowing on a slope, there is a risk of falling more than when going up and down because it is done on a slope with poor footing.

As shown in FIG. 1, two side columns 1 are arranged in parallel to form a support body 2, and a plurality of rectangular treads 3 are provided on both sides of the support body 1 between the left and right side columns 1, 1. The long sides of the footboard 3 are sandwiched by the digits 1 and 1, and are pivotally supported at equal intervals in the longitudinal direction of the support body 2 to form a ladder shape. Then, the other long side of the tread 3 is attached to the left and right sides of the other set of supporting bodies 1, 1, 1.
The two support bodies 2 and 2 are connected to each other by pivoting in.

７を通してある。The step plate 3 is a rectangular plate body,
Its short side is longer than the width of two 1's on the side. Then, as shown in FIG. 3, at the both ends and the central part along the long side of the back surface,
Ribs 4 are provided. At the base of the ribs 4 at both ends, a tubular portion 5 having a hole in the center is provided. The tubular portion 5 has a cylindrical sheath tube having a length equal to or longer than the long side of the tread plate 3. 6 is slidably inserted, and a shaft 7 longer than the sheath pipe 6 is passed through the sheath pipe 6.

Since it is sandwiched at 1, and the length of the sheath tube 6 is uniform,
The support 2 has a constant width from the upper end to the lower end. Further, since the sheath tube 6 is slidably inserted in the hole of the tubular portion 5, the tread plate 3 is freely rotated, so that both support bodies 2, 2 are supported.
Translate longitudinally relative to each other.

As shown in the above, it also moves along the long axis of the long hole. Therefore, the moving range of the support body 2 becomes large, and even when the support bodies 2 and 2 are aligned vertically, the support bodies 2 and 2 can be brought into contact with each other. Therefore, it is possible to move the supports 2 and 2 in parallel with each other in a state of being in contact with each other.

Clip 10 with spring attached to
And a fixed portion 11 provided at the lower end of the telescopic rod 9. The telescopic leg 8 is expanded and contracted by moving the telescopic rod 9 up and down, the length of the telescopic rod 8 is maintained by stopping the telescopic rod 9 with the clip 10, and the telescopic leg 8 is fixed by installing the fixing portion 11 on the ground. Further, since the fixed portion 11 is rotatably attached, it can be installed even on the ground inclined at various angles.

The support 2 on the side of the elongated hole of the cylindrical portion 5 is grounded on the slope, with the side having the telescopic legs 8 facing the slope side of the slope. Then, the support body 2 on the upper side is moved in the direction of warp until the footboard 3 becomes horizontal, and the fixing portions 11 of the telescopic legs 8 provided on the respective side columns 1 are leveled in the direction of warp. Fix it on the ground. At this time, if the ground on which the fixing portion 11 is installed has irregularities, the telescopic rods 9 of the telescopic legs 8 corresponding to the irregularities are adjusted so that the footboard 3 becomes horizontal as indicated by the chain double-dashed line.
